"Windows IT people everywhere owe thanks to Dr. Mark Russinovich, now a technical fellow at Microsoft and his less-famous partner Bryce Cogswell. Russinovich is famous both
as an author, making the technical details of Windows accessible to the
rest of us who dare to think we are technical, and as a programmer,
writing utilities that give us better command of Windows and teach us
about it at the same time.

Russinovich and Cogswell formed the company Winternals and wrote the free Windows Sysinternals tools.
Microsoft bought the company two years ago. Some of the Winternals
products have been relaunched as Microsoft products and others haven't.
But the Sysinternals site remains pretty much as Russinovich and
Cogswell ran it, as they still do, in their spare time, believe it or
not. It's just on microsoft.com now.

A recent video interview with Russinovich
spent quite a bit of time talking about security. I don't necessarily
agree with everything he has to say, which has me re-examining my
beliefs, since I have so much respect for what he has to say. The
interview is 42:39 long, so I'll relate the security-related parts
here, but I certainly recommend watching it yourself (or just listening
as there isn't much in terms of visual action)."
